VINCEN P. MGVOY, 0F MOBILE, ALABAMA.

HosENozzLE.`

To aM whom it may concern.'

Be it known that I, VINCEN P. MoVoY, a citizen of the United States ofAmerica, and resident of Mobile, in the county of Mobile and State ofAlabama, have invented certain new and useful Improvements in I-Iose-Nozzles, of which the following is a specification.

This invention relates to certain new and useful improvements in hosenozzles and it` has for its objects among others to provide a simpleform of nozzle provided with means for producing an effective stream.

I aim further at improvements in the details of construction wherebyimproved results are obtained, such as providing for the control of theadmission of air between the streams, the provision of a strainer ofsufficient area to prevent trash or othersubstance from interfering withthe outer stream and the provision of an extension tube or sleeve tolengthen the nozzle when necessary, and other minor details which willbe more fully hereinafter set forth.

Other objects and advantages of the invention will hereinafter appearand the novel features thereof will be particularly pointed out in theappended claims.

The invention, in its preferred form, is clearly illustrated in theaccompanying drawings, which, with the numerals of reference markedthereon, form a part of this specification, and in which- Figure 1 is anelevation of a nozzle constructed in accordance with my presentinvention. Fig. 2 is a substantially central longitudinalsection throughthe same. Fig. 3 is a cross section as on the line 3-3 of Fig. 1. Fig. 4is an end view. Fig. 5 is a side elevation on a smaller scale showing anextension. Fig. `6 is a detail in longitudinal section with portionsbroken away. Fig. 7 is a similar view showing the parts in a differentposition.

Like numerals of reference indicate like parts throughout the differentviews.

Referring to the drawings, 1 designates the outer casing or body portionof the nozzle. It is formed at one end with the enlargement 2 internallythreaded, as at 3, for .attachment to the hose or an extension soon torbe described incase such is employed. The enlargement 2 is provided withstuds,

as 4,for coperation with a Spanner, as

shown. The casing` or `body portion of the nozzle may or may not betapered toward Specification of Letters Patent.

nut or end cap 6 which may or may not be corrugated or roughened forease of manipulation, the outer end of said nut or cap portion beingreduced, as seen at 7, and in some instances may be provided with anannular channel 8 with which communicate the apertures 9, as seen inFigs. l, 2 and 5, for the purpose of introducing atmospheric air at apoint adjacent the outer stream soon to be described. In some instances,however, this annular channel and the apertures leading thereto may notbe present.

9 is a jam nut sleeved upon the threaded end portion 5 of the casing orbody portion of the nozzle, serving to maintain the cap or end piece inits `adjusted position, ina well known way.

W'ithin the casing or body proper 1 of the nozzle is disposed aconcentric nozzle 10 which may be retained therein in any suitablemanner, in the present instance being shown as provided at apointsubstantially where the taper of the outer casing terminates with anannular boss or enlargement 11 cxteriorly threaded, as at 1Q, andprovided with a shoulder 13, which threaded portion engages the threads14C of the sleeve 15 introduced between the inner nozzle 10 and theouter casing 1 and providing the annular air space 16, as seen best inFig. 2. This, however, is but one of the many ways in which these partsmay be retained in relative position. The sleeve 15 may like- `wise beretained in position in any suitable manner. In the present instance itis shown as provided at its inner end with an annular enlargement; orboss 17 which at substantially diamctrically opposite points is formedwith depressions 18 screw threaded, as at 19, the said screw threadsbeing in alinement with the screw threads 2O of the outer casing 1, asshown best in Fig. 3, and engaging these threads of the casing and thesleeve are the bushings or ferrules 21 which, as will be readilyunderstood upon reference to Fig. 3, serve to retain the sleeveandeasing in relative positions, yet allowing of ready separation whennecessary, also ease of assembling when setting up the nozzle. Thesleeve 15 is formed intermediate the bosses 17 with longitudinalchannels `22, as

clearly seen in Fig. 3, which allow for the passage of the water betweenthe sleeve and the casing.

23 is a sleeve having threaded engagement with threads 24 on the casingl, as seen clearly in Fig. 2. This sleeve 23 serves to cover theopenings 25 formed in the ferrules or bushings 21 and in the sleeve 15,as seen in Fig. 3, and which afford communication between the outeratmosphere and the passageway 1G, so as to admit-air thereto. The sleeveis provided with the perforations 26 which serve to admit the air to theopenings 25 and yet prevent entrance of foreign substances as well asthe shutting 0E of the inow of `air by the hand of the fireman graspingthe sleeve. is seen in Figs. 2 and 3, the sleeve is enlarged in diameterinteriorly between its ends, so as to provide an annular chamber 27between its inner wall and the adjacent wall of the casing 1 so as toinsure sufficient air space at that point.

ln some instances it is desirable to make provision against the entranceof trash or foreign substances into the outer passageway 28 between theouter casing and the inner nozzle 10. This may be accomplished in avariety of ways. ln the present instance l have shown a simple form ofmeans for doing this, which consists of the tapered sleeve or thimble 29having threaded engagement with the threaded inward eXtension 8O of thecasing and its outer end supporting in any suitable manner the inner endof the nozzle 1G, the said sleeve. or thimble being perforated, as shownat 31, which allows suflicient water to pass therethrough into theannular passage 28. lf the perforated sleeve or thimble 29 is notpresent, the inner end of the nozzle 10 may be supported from the innerwall of the casing 10 in any suitable manner.

82 is the annular passage for the outer stream between the outer endportion of the casing 1 and the sleeve 15, see Fig. 2.

The outer end of the sleeve 15 is slightly expanded or flared outwardly,as seen at 33, shown in Figs. 2, 6 and 7, the taper 7 of the inner wallof the reduced portion of the cap or end piece coperating therewith topro'- duce an important result. llihen the outer end of the cap and thesleeve are flush, as seen in Fig. 2, the course of the outer stream isconcentricwith the `inner stream.` By adjusting the nut outward into theposition indicated in Fig. 7, the course of the outer stream isdeflected inward, as indicated by the arrows in said Fig. 7, thusshortening the throw of the stream, whereas by adj usting the nut backbeyond the outer end of the sleeve, as indicated in Fig. 6, the courseof the outer stream is deiiected outwardly.

l sometimes provide an extension to the nozzle, as indicated at 34 inFig. 5. "When this is employed, its threaded end is engaged within thethreaded end 3 of the casing 1 of the nozzle in a well known manner.This extension 34 may be provided with hand grips 35, as shown in F 5.

ln use with the nozzle attached to the hose when the water is turned on,itflows through the central nozzle 10 and through the outer surroundingpassage 28 between the nozzle and the outer casing 1, passing throughthe channels 22 in the boss portion of the sleeve 15 and thence throughthe annular passage 32, around the sleeve and through the passage 35between the outer end of the cap piece 6 and the outer end of thesleeve. At the same time air is drawn in through the apertures in thesleeve 23, if the latter be employed, and thence through the passages 25into the annular air chamber 16, passingout between the inner and outerstreams. The twostreams are thus separated by the intermediate volume ofair. l have also found from vpractical experience that the nozzle thusconstructed with the division of the stream with the intermediate airmost effectually prevents popping and snapping.

From the foregoing it will be seen that I have devised a simple andefficient form of nozzle and while the structural embodiment of the sameas hereinbefore disclosed is what l at the `present time considerpreferable, it is evident that the same is subj ect to changes,variations'and modifications in details, proportion of parts, etc.,without departing from the spirit of the invention or sacrificing any ofits advantages. l, therefore, do not intend to restrict-myself to theexact construction hereinbefore described, but reserve the right to makesuch changes, variations and modiiications as come properly within thescope of the protection prayed.
